title: Tetra-kis(μ-3-chloro-benzoato-κ(2) O:O')bis-[(N,N-di-ethyl-nicotinamide-κN (1))copper(II)].
abstract: In the title centrosymmetric binuclear Cu(II) complex, [Cu2(C7H4ClO2)4(C10H14N2O)2], the two Cu(II) cations [Cu⋯Cu = 2.6314 (4) Å] are bridged by four 3-chloro-benzoate (CB) anions. The four carboxyl-ate O atoms around each Cu(II) cation form a distorted square-planar arrangement, the distorted square-pyramidal coordination geometry being completed by the pyridine N atom of the N,N-di-ethyl-nicotinamide (DENA) mol-ecule. The dihedral angle between the benzene ring and the carboxyl-ate group is 4.49 (11)° in one of the independent CB ligands and 12.00 (10)° in the other. The benzene rings of the independent CB ligands are oriented at a dihedral angle of 84.13 (6)°. In the crystal, weak C-H⋯O hydrogen bonds link the binuclear complex mol-ecules into supra-molecular chains running along [101].
